I'm using org.eclipse.mylyn.wikitext.mediawiki 1.3.0 in order to generate Eclipse Help Content from a MediaWiki wiki

I'm facing the following problem : all images containing underscore character in their name are downloaded on my computer with blank ones instead, but in the html doc, references to images contained the right underscore

Example using the new implementation of mediawiki-fetch-images task:
<mediawiki-fetch-images dest="tmp" url="http://wiki.eclipse.org" pageName="MoDisco/Components/ModelBrowser"/>
